A multi-spatial force field was an extremely powerful form of protective energy screen.

The Borg drone known as "One," created in 2375 aboard USS Voyager, as the result of a transporter accident which caused some of Seven of Nine's nanoprobes to merge with The Doctor's mobile emitter, was equipped with multi-spatial force fields. When Voyager came under attack by a Borg sphere, One beamed aboard the sphere and accessed its navigational controls. He then piloted the Sphere into a proto-nebula, where it was destroyed. One himself survived the destruction of the sphere, by erecting a multi-spatial force field around his body; however, the damage done to his biological systems was too extensive, causing One to die of his injuries shortly thereafter.
